Rich World Must Back 80 Percent Carbon Cuts - Stern
Rich countries must commit to cutting carbon emissions by 80 percent by 2050 and developing nations must agree that by 2020 they too will set their own targets, leading economist Nicholas Stern said on Wednesday. He said the only way the world could defeat the climate crisis was by ensuring that global carbon emissions peaked within 15 years, were then halved from 1990 levels to 20 billion tonnes a year by 2050, and cut to 10 billion thereafter.
